Response Structure

  • (dict) –

    • WhatIfAnalysisName (string) –

      The name of the what-if analysis.

    • WhatIfAnalysisArn (string) –

      The Amazon Resource Name (ARN) of the what-if analysis.

    • ForecastArn (string) –

      The Amazon Resource Name (ARN) of the what-if forecast.

    • EstimatedTimeRemainingInMinutes (integer) –

      The approximate time remaining to complete the what-if analysis, in minutes.

    • Status (string) –

      The status of the what-if analysis. States include:

      • ACTIVE

      • CREATE_PENDING, CREATE_IN_PROGRESS, CREATE_FAILED

      • CREATE_STOPPING, CREATE_STOPPED

      • DELETE_PENDING, DELETE_IN_PROGRESS, DELETE_FAILED

      Note

      The Status of the what-if analysis must be ACTIVE before you can access the analysis.

    • Message (string) –

      If an error occurred, an informational message about the error.

    • CreationTime (datetime) –

      When the what-if analysis was created.

    • LastModificationTime (datetime) –

      The last time the resource was modified. The timestamp depends on the status of the job:

      • CREATE_PENDING - The CreationTime.

      • CREATE_IN_PROGRESS - The current timestamp.

      • CREATE_STOPPING - The current timestamp.

      • CREATE_STOPPED - When the job stopped.

      • ACTIVE or CREATE_FAILED - When the job finished or failed.

    • TimeSeriesSelector (dict) –

      Defines the set of time series that are used to create the forecasts in a TimeSeriesIdentifiers object.

      The TimeSeriesIdentifiers object needs the following information:

      • DataSource

      • Format

      • Schema

      • TimeSeriesIdentifiers (dict) –

        Details about the import file that contains the time series for which you want to create forecasts.

        • DataSource (dict) –

          The source of your data, an Identity and Access Management (IAM) role that allows Amazon Forecast to access the data and, optionally, an Key Management Service (KMS) key.

          • S3Config (dict) –

            The path to the data stored in an Amazon Simple Storage Service (Amazon S3) bucket along with the credentials to access the data.

            • Path (string) –

              The path to an Amazon Simple Storage Service (Amazon S3) bucket or file(s) in an Amazon S3 bucket.

            • RoleArn (string) –

              The ARN of the Identity and Access Management (IAM) role that Amazon Forecast can assume to access the Amazon S3 bucket or files. If you provide a value for the KMSKeyArn key, the role must allow access to the key.

              Passing a role across Amazon Web Services accounts is not allowed. If you pass a role that isn’t in your account, you get an InvalidInputException error.

            • KMSKeyArn (string) –

              The Amazon Resource Name (ARN) of an Key Management Service (KMS) key.

        • Schema (dict) –

          Defines the fields of a dataset.

          • Attributes (list) –

            An array of attributes specifying the name and type of each field in a dataset.

            • (dict) –

              An attribute of a schema, which defines a dataset field. A schema attribute is required for every field in a dataset. The Schema object contains an array of SchemaAttribute objects.

              • AttributeName (string) –

                The name of the dataset field.

              • AttributeType (string) –

                The data type of the field.

                For a related time series dataset, other than date, item_id, and forecast dimensions attributes, all attributes should be of numerical type (integer/float).

        • Format (string) –

          The format of the data, either CSV or PARQUET.
